Lars Hofhansl commented on HBASE-12972:
---------------------------------------

[~giacomotaylor], let's figure out what Phoenix needs. That would be a good starting point.

> On HBASE-12566, [~lhofhansl] proposed:
> {quote}
> Maybe we can have a {{Region}} interface that is to {{HRegion}} is what {{Store}} is
to {{HStore}}. Store marked with {{@InterfaceAudience.Private}} but used in some coprocessor
hooks.
> {quote}
> By example, now coprocessors have to reach into HRegion in order to participate in row
and region locking protocols, this is one area where the functionality is legitimate for coprocessors
but not for users, so an in-between interface make sense.
> In addition we should promote {{Store}}'s interface audience to LimitedPrivate(COPROC).
